Disc-shaped aircraft with dual spinning discs

Abstract

Disclosed is a disc-shaped aircraft with dual spinning discs, comprising an engine, an upper fuselage, a lower fuselage, an upper spinning disc and a lower spinning disc. An upper cover is arranged at the bottom of the upper fuselage, and a lower cover is arranged at the top of the lower fuselage. The upper and lower covers are connected as a whole through an axle tube. A central gear is installed on the axle tube. The lower spinning disc is installed on the central gear and the upper spinning disc is located above the lower spinning disc. The engine is fixed on the lower cover and drive the central gear so that the upper and lower spinning discs are driven to rotate. Helical blades of the upper and lower spinning discs are opposite in rotary direction, angle of attack and installation angle, so that the problem of rotary balance of the fuselage is solved. The disc-shaped type aircraft provided by the invention is simple in structure, light in weight and low in cost, and can save much lifting power.

What is claimed is: 
     
       1. A disc-shaped aircraft with dual discs configured to spin, comprising: an engine, an upper fuselage, a lower fuselage, an upper disc configured to spin and a lower disc configured to spin, wherein a glass top cover is disposed above the upper fuselage, a bottom cover and legs are disposed under the lower fuselage, and a hatch cover is provided on the bottom cover, wherein:
 an upper cover is disposed at a bottom of the upper fuselage, and a lower cover is disposed at a top of the lower fuselage; the upper and lower covers are connected integrally via an axle tube which passes through central holes thereof; a central gear is mounted on the axle tube via an axle tube bearing; the engine is fixed on the lower cover, and an output shaft of the engine is engaged with a driving gear by means of a bevel gear; the driving gear is engaged with the central gear; a tension ring, a lower portion of which is fixed to the upper cover, is mounted on an exterior of the upper fuselage; 
 an upper bearing ring is mounted on the upper fuselage, and a lower bearing ring is mounted on the lower fuselage wherein the upper bearing ring is fixed on an upper portion of the tension ring; the lower bearing ring is fixed on the lower cover; and bearing races are respectively arranged on a lower surface of the upper bearing ring and an upper surface of the lower bearing ring; 
 the lower disc comprises: a lower disc inner ring connecting plate, a lower disc inner ring fixed on the outer periphery of the lower disc inner ring connecting plate, a lower disc outer ring concentrically disposed with the lower disc inner ring, and helical blades disposed between the lower disc inner ring and the lower disc outer ring, wherein both upper and lower surfaces of the lower disc inner ring are provided with bearing races; the lower disc is engaged on the central gear by a sprocket hole which is disposed at a center of the lower disc inner ring connecting plate; and the bearing races on the lower surface of the lower disc inner ring are operatively cooperated with the bearing races on the upper surface of the lower bearing ring by means of rotation of rolling balls; 
 the upper disc, which is located above the lower disc, comprises: an upper spinning disc inner ring, an upper spinning disc outer ring concentrically disposed with the upper disc inner ring, and helical blades disposed between the upper disc inner ring and the upper disc outer ring, wherein both upper and lower surfaces of the upper disc inner ring are provided with bearing races; the bearing races on the upper surface of the upper disc inner ring are operatively cooperated with the bearing races on the lower surface of the upper bearing ring by means of the rotation of balls configured to roll; and 
 at least three guide wheels are disposed on the tension ring, wherein the guide wheels are placed between the upper disc inner ring and the lower disc inner ring, and are respectively cooperated with the bearing races on the lower surface of the upper disc inner ring and the bearing races on the upper surface of the lower disc inner ring by means of rolling. 
 
     
     
       2. The disc-shaped aircraft with dual discs as claimed in  claim 1 , wherein toothed tracks are disposed at outer sides of the bearing races which are arranged on the lower surface of the upper disc inner ring and the upper surface of the lower disc inner ring; and the tension ring is provided with at least three guide gears, which are placed between the upper disc inner ring and the lower disc inner ring, and respectively engaged with the toothed tracks on the lower surface of the upper disc inner ring and on the upper surface of the lower disc inner ring. 
     
     
       3. The disc-shaped aircraft with dual discs as claimed in  claim 2 , wherein the guide gears are uniformly arranged among the guide wheels. 
     
     
       4. The disc-shaped aircraft with dual discs as claimed in  claim 1 , wherein the helical blades are radially distributed around the axel tube. 
     
     
       5. The disc-shaped aircraft with dual discs as claimed in  claim 1 , wherein windward sides of the helical blades are arranged in an elevation angle. 
     
     
       6. The disc-shaped aircraft with dual discs as claimed in  claim 1 , wherein a top side of any one of the helical blades and a bottom side of the helical blade which is adjacent to the aforesaid one are located in a same vertical plane. 
     
     
       7. The disc-shaped aircraft with dual discs as claimed in  claim 1 , wherein hatch doors are separately disposed at corresponding positions of the upper and lower covers and the lower disc inner ring connecting plate.
